Learning Correlated Equilibria in Mean-Field Games

no code implementations22 Aug 2022 Paul Muller, Romuald Elie, Mark Rowland, Mathieu Lauriere, Julien Perolat, Sarah Perrin, Matthieu Geist, Georgios Piliouras, Olivier Pietquin, Karl Tuyls

The designs of many large-scale systems today, from traffic routing environments to smart grids, rely on game-theoretic equilibrium concepts.

Learning in Mean Field Games: A Survey

no code implementations25 May 2022 Mathieu Laurière, Sarah Perrin, Julien Pérolat, Sertan Girgin, Paul Muller, Romuald Élie, Matthieu Geist, Olivier Pietquin

Non-cooperative and cooperative games with a very large number of players have many applications but remain generally intractable when the number of players increases.

Scalable Deep Reinforcement Learning Algorithms for Mean Field Games

no code implementations22 Mar 2022 Mathieu Laurière, Sarah Perrin, Sertan Girgin, Paul Muller, Ayush Jain, Theophile Cabannes, Georgios Piliouras, Julien Pérolat, Romuald Élie, Olivier Pietquin, Matthieu Geist

One limiting factor to further scale up using RL is that existing algorithms to solve MFGs require the mixing of approximated quantities such as strategies or $q$-values.

Generalization in Mean Field Games by Learning Master Policies

no code implementations20 Sep 2021 Sarah Perrin, Mathieu Laurière, Julien Pérolat, Romuald Élie, Matthieu Geist, Olivier Pietquin

Mean Field Games (MFGs) can potentially scale multi-agent systems to extremely large populations of agents.

Mean Field Games Flock! The Reinforcement Learning Way

no code implementations17 May 2021 Sarah Perrin, Mathieu Laurière, Julien Pérolat, Matthieu Geist, Romuald Élie, Olivier Pietquin

We present a method enabling a large number of agents to learn how to flock, which is a natural behavior observed in large populations of animals.

Scaling up Mean Field Games with Online Mirror Descent

1 code implementation28 Feb 2021 Julien Perolat, Sarah Perrin, Romuald Elie, Mathieu Laurière, Georgios Piliouras, Matthieu Geist, Karl Tuyls, Olivier Pietquin

We address scaling up equilibrium computation in Mean Field Games (MFGs) using Online Mirror Descent (OMD).

Fictitious Play for Mean Field Games: Continuous Time Analysis and Applications

1 code implementation NeurIPS 2020 Sarah Perrin, Julien Perolat, Mathieu Laurière, Matthieu Geist, Romuald Elie, Olivier Pietquin

In this paper, we deepen the analysis of continuous time Fictitious Play learning algorithm to the consideration of various finite state Mean Field Game settings (finite horizon, $\gamma$-discounted), allowing in particular for the introduction of an additional common noise.

Machine Learning Optimization Algorithms & Portfolio Allocation

no code implementations23 Sep 2019 Sarah Perrin, Thierry Roncalli

Nevertheless, very few models have succeeded in providing a real alternative solution to the Markowitz model.
